I'm new to the forums, and I don't own a G35 just yet but I will now that I"m graduating. I'm trying to get a feel for whats out there FI wise for them. Reading over this forum, it is fairly complicated to understand the differences between different kits-and what you have to do to the engine to run the different ones.

Basically what I m wondering is, which turbo/supercharger kit would you recommend and why? Also what changes (if any) have to be done to the stock engine to avoid detonation? I will barely have the 5-8k$'s required to buy the turbo/SC let alone a new engine.

I've heard of the APS TT, the Turbonetics, and the Vortech SC- what are the trade off's between these as examples?

I appreciate any info, I've learned so much from these forums.

 

Sorry to be a little rude, but this is your friend: https://g35driver.com/forums/search.php

There is no way to answer your questions in one thread, let alone one post. Sorry...

 

ha yea like he said hate to bust your bubble but your gonna have to spend some time looking for the information. im in the same exact situation right now as you are with graduating soon. ive just been reading tons of forums on the g35s and turbos, superchargers, exhaust, and everything i can learn about them. I wanna know all i can when i get mine. As for finding more information on g35s look at some of the 350z website as most of them have lost more information regarding the turbo applications for these vehicles most because they fit g's as well

 

If $5-$8k is your price range stick with a supercharger or at the very most single turbo. The price tag on the APS TT is around $7500 plus the cost of gauges and install, you'll easily hit $10k. With the Greddy you'll be spending just about the same when you take all of the steps to prevent detonation. APS single turbo has a group buy going for around $5,290 but again once you figure in the cost to install and everything else you'll be right at $8,000.

I think you can get the vortech for around $4k-$5k. Plus a supercharger will be safer from what I've seen. The only trade off is some people are selling their superchargers for turbo kits

 

Like tony said. Go supercharger or single turbo with your budget. I am one of the guys that sold his s/c to go Twin Turbo. For the difference in price I would say go the single turbo instead of the s/c. It is only $400-$800 more. Install will be about the same for both. If you go APS ST you won't have to pay for a tune because it come already tuned. It also has a upgraded fuel system. The best part about turbo is if later on you want more power all you have to do it boost unlike with a s/c you will have to buy a bunch of bolt ons that can get quite expensive and you still won't gain that much.

 

Thanks for the repsonses guys, sorry it's such a general topic- I was just trying to get a general understanding of what people were using in their cars and why. That info is usually spread across so many forum postings it would take forever to search, but I'll keep looking around.

Anyhow, I took a look at the APS ST- and I was wondering, on the APS website it's only listed for 350Z's. From what I gather, parts are nearly interchangeable between the 350Z and the G35, is that why the kit works for the G35 as well? Also, can I expect to see the same horsepower gains listed on their site (upto around 385 or so)? And with this sytem, would I have to do any other engine mods or would stock engine do? Would I have to replace the front bumper with a more open one for increased airflow? Sorry for all the newbie questions.

 

As far as the bumper, I don't think that is necessary but it would help with cooling.

 

I've been all over the bumper thing for the past month, my concern is the efficiency of the intercooler with the stock bumper. I came to the conclusion that I'll keep my nismo bumper and get a water injection kit, which would help with the intercooler. I do not consider water injection to be THE alternative, but just an ounce of prevention.

The fitment on the APS single turbo system should be similar on the G35 as it is on the 350Z. APS hasn't confirmed this as of yet, but looking at the pictures and having a good understanding of what is under the car it will be possible one way or another.

Strangely APS is seeing better response out of the G35 than they are the 350Z on their TT system, maximum boost is hitting at 2500rpms which is pretty low. You can expect similar horsepower gains between the 350Z and G35. Be sure to read the dyno's closely though, some of those pulls are with a true dual exhaust, and 94 octane map (not easily available right now)

I've never owned a turbocharged car, my G35 will be the first and I recommend doing a LOT of research if you have limited experience. You'll feel a lot more comfortable with the decision you are making if you know what is going on under the hood. A book called Maximum Boost by Corky Bell is one of the best sources of information on turbocharging available.

Feel free to ask any questions you have. I know some have told you to use the search function but there is a limited amount of information on forced induction on G35Driver so I understand. I was in your shoes once so I know how it is.
